JGC-30型称重给煤机在混喷输煤系统中的应用

Application of JGC-30 Weighing Coal Feeder to Conveying System of Coal Mixed Injection

天铁动力厂在高炉送煤粉混喷改造工程中,输煤系统新装3台JGC-30型称重给煤机,结合其实际应用情况,介绍了称重给煤机的工作原理及控制系统。阐述了如何通过变频器及PLC精确控制皮带输送恒质给料,从而达到最佳配比实现节能环保,提高经济效益。

Three new JGC-30 weighing coal feeder were installed in coal conveying system during BF coal mixed injection modification at Tiantie Power Plant.The paper explains the working principle and control system of coal feeder in combination with practice and expounds how to precisely control the belt to supply coal in constant flow with frequency converter and PLC,so as to achieve optimal distribution ratio,save energy,and protect the environment and increase economic benefit.
